President Trump’s announcement that he would officially declare the opioid epidemic a national emergency could lead to greater access to grant funding and would waive rules to expand access to opioid treatments, experts say.

Trump said Thursday that his administration is working on the paperwork to make the declaration, just two days after Health and Human Services Secretary Tom Price said Trump wasn’t going to make the declaration. Previous declarations have been made for the Zika virus and natural disasters such as Hurricane Sandy.
